Description

  The present invention relates to a suitcase caster set structure, and more particularly to an original suitcase caster set structure with a brake function.

  Due to the structural design of the suitcase, in order to avoid the sliding movement that occurs when the user does not touch the suitcase, there is a structure that can control the slippage of the caster (or leg ring) of the suitcase in the industry. Although related technology may be referred to a patent previously developed by the inventor of the present invention, Taiwan Patent No. M408272 “suitcase structure with caster anti-slip function”, the related art is generally known. The suitcase structure posted in the proposal is a structure comprising a push button switch, a direction changing drive module, a rope and a brake unit, etc., and can control the braking or releasing of the caster. It has become.

  However, when the conventional suitcase caster structure with a brake function is actually applied, the following problems exist.

  Many conventional suitcase casters are provided so that they can turn freely, and the brake unit of the caster is usually provided so as to pass through the center of the positioning table, where the suitcase was braked. Since each of the units of the brake unit and between the brake unit and the caster are pulled strongly against each other, abutting and rubbing, the caster that can originally turn freely has an effect at that time. However, if the user or another person hits the suitcase, the caster will be forced to turn and damage to the brake unit will occur. There is a disadvantage that there is a risk of giving it, and it is necessary to improve it.

  In view of this, the inventor has many years of experience in the manufacture and development and design of related products, and after having designed and carefully evaluated the above-mentioned goals, finally obtained a practical invention. .

  The purpose of the present invention is to provide an improved caster set structure with a brake function for a suitcase, and the problem to be solved is to develop a new suitcase caster set structure that is more ideal and practical. is there.

  The suitcase caster set provided at the bottom corner of the case body of the suitcase, and as a technical feature to solve the problems of the present invention, is provided with a positioning base comprising an attachment portion and a caster combination portion The caster combination part is provided with a bearing hole, and is provided with a caster holder capable of rotating in a direction including an upper side and a turning side, and the upper side is provided near the caster combination part of the positioning table. In the center of the upper side, a fixing shaft plug for insertion into the bearing hole is provided, so that the turning side turns and changes direction, and on the turning side of the caster holder capable of rotating in the direction. The caster provided, the working space recessed between the swiveling side and the upper side of the caster holder capable of rotating in the direction, the limit wall provided on one side of the working space, and the fixing shaft plug An interlocking bar that is inserted into the through hole and can be operated up and down is provided. The upper part of the interlocking bar protrudes upward on the caster combination part on the positioning base, and the bottom part of the interlocking bar faces downward in the working space. There is an abutment block that is provided in the working space and is connected to the bottom of the interlocking bar. One side of the abutment block is spaced from the caster area. The brake surface is provided, and the other side of the abutment block is provided with a sticking surface for sliding and sticking to the limit wall, and a flexible reset unit provided at a position corresponding to the interlocking bar is provided. It has a pull-up function that allows the interlocking bar to have a lift-reset function and extends to the pulling side connected to the control device in the suitcase and to the positioning table. A pulling line comprising a side, and a direction change drive module provided between the upper part of the interlocking bar and the end of the pulling line, so that the pulling force of the pulling line is pressed against the interlocking bar. It is designed to change to a downward pushing force, and it has a pivotable connection provided between the abutting block and the bottom of the interlocking bar, so that the abutting block can freely rotate according to the interlocking bar This suitcase caster set is made possible. By this design, compared with the background art, the abutting block can freely rotate with the interlocking bar as a pivot point even when the abutment block is in contact with the caster and the brake is pressed. In addition, even in the brake state, the caster holder capable of rotating in the direction can freely turn, and at the same time, there is practicality and inventive step that the associated parts such as the interlocking bar and the direction changing drive module are not damaged. .

  As another technical feature of the present invention, the other side of the abutting block is provided with an affixing surface for sliding and affixing to the limit wall, and the abutting block holds the caster, and the brake state When this happens, the abutment block side has a support force that enables stable positioning, and the braking force and stability are further improved.

  As another technical feature of the present invention, a pulling rope guide frame having a curved extending portion and a sticking portion is further provided on the mounting portion of the positioning table. There is a limitation on the position to guide the bag so that it can be attached to the suitcase body side, and there is an advantage of reducing the space for the towline.

The fact of the effect improvement by this invention is as follows.
In the "caster set structure with a brake function of a suitcase" posted in the present invention, an original structure in which a further pivotable connection is provided between the abutting block and the bottom of the interlocking bar Therefore, compared with the conventional technology described in [Background Art], the present invention makes it possible for the abutment block to move the interlocking bar even when the abutment block is in contact with the caster and a brake is applied. The caster holder that can turn freely even when in the brake state at the same time as turning freely as an axis, can turn freely, and practicality that it does not damage related parts such as interlocking bar and direction change drive module, There is an inventive step.

The new effects of the present invention are as follows.
1. Due to the technical feature that the other side of the abutting block is provided with an affixing surface for sliding and affixing to the limit wall, when the abutting block applies a brake that holds the caster The bearing block has a supporting force that enables stable positioning, and the braking force and stability are further improved.

2. A pulling line guide frame provided with a curve-shaped extending part and a sticking part is further provided on the mounting part of the positioning table so that the pulling line is attached to the suitcase case body side. There are restrictions on the position to guide, and there is an advantage of reducing the space for the towline.

  The contents described in the above-described embodiments are contents used for specifically explaining the present invention, and have been described in technical terms in the sentence. Even if a person skilled in the art makes changes or modifications based on the concept or idea of the present invention and obtains an equivalent effect, all claims are within the scope of the claims of the present invention. Shall be included.
